CONVERTIBLE BOAT-PROPELLING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 14,766, dated December 2, 1902.

Application filed January 29, 1902, Serial No. 91,797. (No model.)

T0 at whom, it may concern:

Be it known that .1, JAMES WHITESIDE, a subject of theKing of Great Britain, and a resident of New York city, county and State of New York, have invented certain new and useful Improvements in Convertible Boat- Propelling Apparatus, of which the following is a specification.

My invention consists of improved means of converting boat-propelling apparatus for use of the boat either in the water or on ice, as hereinafter described, reference being made to the accompanying drawings, in which- Figure 1 is partly a longitudinal vertical section and partly a side elevation of a boat that may be used in the water with screw propelling apparatus with apparatus applied for propelling it on ice, said apparatus being in terchangeable with the apparatus for use in the water. Fig. 2is aplan view of the same with some parts broken out. Fig. 3 is a detail intended to indicate the application of the same principle to paddle-wheel boats.

A represents a small boat of ordinary construction, such as may have any suitable motor for propelling it by a screw mounted at the stern of the boat on a shaft h, having the power of the motor applied in any approved way of common knowledge, which it is unnecessary to show. To adapt such a boat for use on ice with the same power apparatusfor propelling it, I provide a sleighrunner attachment of any approved construction whereon it may be mounted, as on the runners c, suitably for carrying the boat. In this example the connection is made by means of posts or knees d resting on the runners and at their upper ends attached to the sides of the body of the boat, as at 6, so

as to be readily detachable, with the upturned ends of the runners also attached at f to the sides of the bow-quarters and with a crossbar 9 connected to standards g on the hind ends of the runners, thus utilizing the body of the boat as part of the ice-boat structure; but it is obvious that the body structure of the ice-boat may be a crib or cradle of complete structure independent of the boat and adapted for receiving the boat and properly holding it without any special connection of the two.

A bevel gear-wheel h is substituted in the place of the usual propelleron the propellershaft 1), which gears by another wheel j with a transverse shaft t, supported in suitable bearings 70, supported on the runners c, and behind this shaft and parallel with it a propelling-shaft Z is carried in the rear extremi ties of arms m, pivoted at n to the hind posts cl of the runners, or it may be to any attachment to the runners, as the crib or cradle above referred to, if used, and on this shaft Z one or more spike-wheels or drums o are mounted for propelling the runners by engaging the ice and being rotated by suitable connection of said shaft Zwith the shaft 1;, as the belts p and pulleys q r, or other approved means. The arms on being pivoted at their connection with the posts 01 enable the spikewheels to rise and fall automatically for passing any irregularities in the surface of the ice, such as are often encountered. To prevent clogging of the spikes, clearing-teeth to may be attached to bar g, said teeth extending into the spaces between the spikes.

In Fig. 3 t may be considered asection of the side of a paddle-wheel boat, and a a spikewheel substituted for a paddle-wheel on the usual paddle-wheel shaft '0 to indicate the same principle applied to a paddle-wheel boat.

Thus the usefulness of small boats on rivers, lakes, and other bodies of water subjectto freezing over in winter may be considerably.

increased.

What I claim as my invention is 1. The combination with a boat and power apparatus adapted for propelling it in water, of a runner attachment of detachable application adapted for carrying the boat on ice and a propeller adapted for working on the ice and geared with the water-propeller shaft by a wheel that is interchangeable with and is substituted for the water-propeller directly on the water-propeller shaft, said shaft being the same on which the water-propeller is directly applied.

The combination with a boat and power apparatus adapted for propelling it in water, of arunner attachment of detachable application adapted. for carrying the boat on ice and a propeller adapted for working on the ice and geared with the water-propeller shaft by a wheel that is interchangeable with and is substituted for the Water-propeller directly on the water-propeller shaft, said shaft being peller-shaft, and also geared with the spiked the same on which the water-propeller is didrum-shaft. 1o
